Application March 28, 1949,'Serial No.V 8f3-,799' -1 2 Claims. (o1. 15s-.134i

This invention relates to stools, particularly those commonly employed adjacent a counter or the like and has to do with the base structure-| thereof, irrespective of the precise nature of the stool or its use.

It is the primary object of this invention to provide a stool base structure having novel means of interconnecting the component parts thereof and joining the entire assembly rigidly to a floor or the like, all capable of quick and easy attachment or removal without the use of special tools or without the necessity of particular skill in the assembling operation.

It is the most important object of the present invention to provide stool structure having a base provided therein with means for rigidly securing the same to a iloor that is easily accessible at the top thereof and having a vertical column removably secured thereto and provided with attaching means disposed exteriorly 'of the column, all to the end that the latter may be attached to the base as the last step of the assembling operation.

Other more minor objects will be made clear or become apparent as the following specification progresses, reference being had to the accompanying drawing, wherein:

Fig. 1 is a perspective view of a counter stool made in accordance with my present invention.

Fig. 2 is a vertical cross-sectional view taken on irregular line II-II of Fig. 1.

Fig. 3 is a transverse cross-sectional view taken on line III-III of Fig. 2; and

Fig. 4 is a cross-sectional View taken on line IV-IV of Fig. 2.

The stool forming the subject matter of this invention includes a hollow base I0, a vertical cylindrical column I2, a tripod I4 and a seat, broadly designated by the numeral I6.

The hollow base I is substantially frustoconical and has its greatest diameter next adjacent a oor or the like I8 upon which base I8 rests and is Secured. A floor plate 20. resting directly upon oor I8 within the base I is disclike and secured to floor I8 through the medium of a plurality of screws 22 or other fastening elements depending upon the construction of the oor I8.

Plate 2D has a centrally disposed offset portion 24 that is centrally perforated for receiving a vertical bolt 2S and formed to prevent rotation of polygonal head 28 of bolt 26. The top wall of the base I0 includes a cross-bar 38 and an annular up-turned ange 32. The cross-bar 38 has a central opening 34 for receiving the bolt 25 access.

2;; that extends a distance above plate Z to receive a nut 36.

The outside diameter of the column I2 is substantially the same as the inside diameter of ilange 32 to the end that the former rests directly upon shoulder 38 formed on base I0. A bearing plate 46 crosses the uppermost end of the column I2 and has an opening 42 formed therein for rotatably receiving a spindle 44 forming a part of the tripod I4.

A pair of elongated, vertical rods 46, disposed within the column I2, is threadably mounted or otherwise removably secured at the loWermost ends thereof within the cross-bar 38, there being one bar 46 on each side of the opening 34. The uppermost ends of the rods 46 pass through the bearing plate 40 and have nuts 48 thereon disposed exteriorly of the column I2.

Tripod I 4 includes, in addition to the spindle 44, spider arms 50 that are in turn secured rigidly to the seat I6 in any conventional manner.

Seat I6 usually includes a pad 52 having a ring 54, the latter of which is provided with structure underlying the pad 52 for connection With the spider arms 50.

It is clear from the foregoing that in mounting the entire stool upon floor I8, the operator first aflixes the plate 20 in the desired position by fastening screws 22 after rst positioning bolt 26 to receive base I8. Base IB is thereupon placed over the plate 29 and bolt 26 projects through the opening 34 of cross-bar Sl in the manner shown in Fig. 2. Since the uppermost end of bolt 26 is exposed and easily acessible, the operator can turn the nut 36 to draw base III tightly against floor I8.

The next step in the assembling operation is to aix the rods 46 into the cross-bar 30, whereupon column I2 is threaded over the rods 46 and disposed with its lowermost end resting upon shoulder 38. The operator then places the bearing plate 40 in position over the rods 4e and applies nuts 48, both of which are exposed for easy When the nuts 48 are drawn tight, the column I2 will be held tightly against the shoulder 38 of the base Il. The tripod I4 aflixed to the seat I may then be removably mounted within the opening 42 of bearing 48 for free rotation therein.

It is apparent that no special tools are needed for the assembling operation as above set forth, or for disassembling as desired. Furthermore, no particular skill is needed and the entire structure may be shipped in a knocked-down condition with only the simplest instructions concern- 3 ing mounting of the stool upon a floor or the like.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a stool of the kind described, a hollow base having a top; a plate in the base having means of attachment to a oor; parts on said plate and extending through said top of the base for holding the latter against the oor; a column covering said top of the base and extending upwardly therefrom; a number of rods in the column, said rods being removably secured at the lowermost ends thereof to said top of the base; and means at the uppermost end of the rods for releasably holding the column against the base.

2. In a stool of the kind described, a base; means for removably securing said base to a floor; a column extending upwardly from said base; a number of rods in the column secured GWYLM H. BOZARTH.
